Be it known that I, THOMAS REDMAN, a subject of the King of Great Britain and Ireland, and resident of Green Royd, Arnside, in the county of Westmoreland, England, have invented a certain new and useful Improvement in and Relating to Shuttles for Weaving, of which the following is a a specification.

This invention relates to that class of shuttles such as are commonly used for weaving ordinary cotton and like fabrics; and the object is to construct and combine the several parts of the shuttle tongue, so that the two ends of the shuttle are more evenly balanced than is the case when the shuttle tongue and adjacent parts are constructed solid in the manner as hitherto; also to be enabled to adjust the elevation of the point or free end of the shuttle tongue in relation to the base of shuttle.

In the accompanying drawings, Figure 1. represents one end of an ordinary shuttle to which my invention is added, Fig. 2 is a transverse section through line a. b. Fig. 3 is, an enlarged view of a metal plate stamping such as may be used for blocking into a hollow box base of a shuttle tongue. The remainder of the figures are also drawn to a larger scale, Fig. 4: re resenting a side elevation of a tube to whic the box base of shuttle tongue is secured. Fig. 5. is a plan of same showing by dotted lines the engagement of the projecting or skewer por tion of shuttle tongue. Fig. 6 shows the side and end views of a split tubular bearing bar adapted to engage with the underside of the hollow box base. Fig. 7. is an elevation of a split tubular bar adapted to act as a pivot upon which the hollow box base may be supported. Fig. 8. is a section of said tubular bar, and Fig. 9. a view of the hollow box base partly in section.

In carrying out my invention, I form a square sectioned hollow box base of shuttle tongue, from a metal plate stamping, such as shown by Fig. 3. hereinafter more particularly described. The piece of plate indicated by the numeral 2. is out along the dotted line A, into contact with the adjacent portion of plate, see Fig. 9. When the plate stamping is pressed in the ordinary manner by suitable dies, it is bent to the contour of said dies. To this operation no claim is made as forming part of this invention. The side portions 2 of the metal plate stamping, and the end portions indicated by E and F, when the plate is blocked, are bent intoa vertical position along the dotted lines 2 also along the full lines 3 the portions 2 of the plate when blocked, forming the vertical sides of the hollow box base. See Fig. 2. The'end portions of the stamping indicated by E and F. are out along the full lines C. B, and said pieces along with the center piece C, are perforated at H, J, and K, the center portion C, being bent into a vertical position along the dotted lines C, E and F. The pieces E and F are as before stated bent into a vertical position along with the side portions 2". Each piece E and F is respectively bent along the dotted lines E and F, in order to strengthen the front end of hollow box base, which is then composed of three thicknesses of plate, G, E, and F, temporarily held together in the desired position by the engagement of the clips G of ordinary construction bent over the front by which the plates are held together. See Fig. 9. When the blocking of hollow box base 3 is formed up, and temporarily held together by the clips G, the top and rear end of said base are open. This opening is covered by a plate P. the said plate overlapping the front end of box base by the turned down piece G. See Fig. 9.

The perforations 5. through the side portions 2 are opposite each other when blocked, and through these perforations is passed a tube 6, the said tube also passing through and engaging with a tube 6 which may be flanged at 7 or otherwise, the tube 6 being of such length as to engage with the inner vertical surfaces of the side plates 2*, the ends of the tube 6 terminating by preference flush with the outer vertical surfaces of 2 The tube 6 has an extension 6 projecting at right angles thereto, as

when the hollow skewer portion of, shuttle I thereon, and finally secured by the process of'soldering, as may also be secured-the other parts of the shuttle tongue and box base, thereby firmly uniting the parts. The

tongue 7 shown bydotted lines, is pressed tube 6 passes through the tube 6 which is secured within vthe hollow box base. The said tube 6 passing through the perforations 5, is mounted upon a hollow bar 8, split longitudinally and provided with an internal flange 8 see Figs. 7 and 8, the tubular bar acting as a support upon which the box base 30f shuttle tongue 7 is pivoted. The said bar engages with holes in the shuttle block '9,b o'red somewhat less in diameter than the external diameter of the tubular bar 8, when the latter is not compressed by engagement with said holes in the shut.- tle block, the tube 6 being free to turn on tiibularbar 8', when. it'is mounted within the opening 95in shuttle block, 9.

The short curvature 3 at the rear of hol-' low box base 3. is radial fromthe center of pivotingsplit tubul'arbar 8. The curvature may be strengthened by'e'xtending the plate P over same, as shown by Fig. 9; This curvature engages with a flat plate spring 10.

placed in an. undercut channel 11. formed in the shuttle block 9, the spring being of such form. as to hold the base 3 and attached "skewer of tongue 7 firmly within the shuttle perforation, and not require the aid of spring supporting pins passing through theshuttle block The. regulation of the vertical distance between the base of shuttle block -9.. and the free end or point of the skewer of shuttle tongue, maybe adjusted by a split tubular bar 12, arranged with a longitudinal depression 12 formed in the circumference of said tubular bar. I v

Theunderside of thehollow box base 3.

rests upon the depression 12". so thatv on turning the barl2 in a rotary direction, on one edge of the depression engaging with the hollow base 3, the point of the skewer of shuttle tongue is adjusted, to the position required inrelation to the position of shuttle eyelet through which the yarn as it is delivered passes. V By constructin Z the box base 3 and the skewer of tongue ollow, along with the adjacent parts 8 and'12. the end of shuttle to which the tongue is pivoted, is of less weight than when said parts are solid and provided with an ordinary spring requiring supporting pins, thus by bringing the twoends of the shuttle into more even balance, a more tendants is reduced, consequent upon the reduction of, the liability of the shuttle flying out of its desired path.

- What I claim is I 1. The combination with a shuttle casing and shuttle tongue, of means for mounting said tongue in said casing, comprising a hollow box, supporting means within said box adapted to engage the end of said shuttle tongue, a member passing through said supporting means and having its ends engaging the shuttle casing to provide a pivotal support for the shuttle tongue, substantially as described. r

' 2. A loom'shutt'le comprising in combination a shuttle casing-having a recess'formed therein, a shuttle tongueprovided with a hollow skewer, a hollow box -pivota lly mounted within said recess-, supporting meanswithin said box adapted to-engage the hollow skewer of the shuttle -tongue and adjusting means located beneath the forward-end of the hollow box for adjusting the position of the shuttlet'ongue' in relation to the base of the shuttlecasi-ng.

3. A loom shuttle comprisingincombination a shuttle casing; having a recess formed therein, a shuttle tongue provided with a hollowskewer, a hollow box pivotally mounted. within said recess, supporting means within said box adapted to -eng'age the hollow skewer of. the shuttle, tongue, adjusting means located beneath the forward end of, the hollow box for adjusting the position of-the shuttle tongue in relation to the base of the shuttle casing, and spring means within said recess adapted to bear against the hollow box, substantially as described. V V r V 4:. A loom shuttle comprising in combina tion a: shuttle casing having a recess formed therein near its end, a shuttle; tongue provided with a hollow skewer,- a splittubula-r member transversely disposed within said recess, supporting means adapted to-engage the end of said skewer pivotally carried on said tubular member, a hollow box casing surrounding said supporting member and also pivotally' carried on said-tubular meme ber, a'flat spring located within said recess 7 and bearing against the lower rearward edge of said hollow box and? resilient ad-' said tongue in said casing, comprising a port for the shuttle tongue, substantially as hollow sheet metal box, supporting means described. Within said box engaging the end of said shuttle tongue, a member passing through THOMAS E said supporting means and'the sides of said Witnesses: sheet metal box and having its ends engage THOMAS B.
